14 Common Causes of High Bilirubin

Bilirubin is a substance produced when the body breaks down old red blood cells. It travels in the bloodstream and is processed by the liver before leaving the body. The liver and bile play a role in moving bilirubin along, and levels can vary for many reasons.

Changes in bilirubin can be influenced by everyday processes, how the liver handles substances, and the movement of bile through the body. Different factors can contribute to temporary shifts in bilirubin without indicating a serious issue.

This article reviews 14 factors commonly associated with higher bilirubin levels. It explains these influences in simple terms, describing how bilirubin is naturally produced, transported, and processed. Readers will gain a general understanding of the different factors that can affect bilirubin levels and how this substance interacts with the liver and bile, all without suggesting medical evaluation or treatment.

1. Gallstones

Bile is a fluid produced by the liver that helps move substances through the digestive system. Occasionally, small solid pieces can form in the gallbladder. These pieces vary in composition, with some made mostly of cholesterol and others containing different compounds naturally found in bile.

When these solids develop, they can influence how bile flows through the gallbladder. Factors like individual body chemistry, inherited traits, and typical diet patterns can affect how solids form and move. The formation of these solids is a natural process within the gallbladder, and their presence can alter the way bile travels through the digestive tract.
